The green pellet making studies was done with the intention of consuming a least amount of binder for getting optimum green pellet strength at minimum possible Blaine number (SSA) . Higher blaine number will translate in to higher energy requirement for grinding [ 10 ]; hence, lower blaine number of iron ore is preferred.
The blaine number of iron ore concentrate is important for pellet feed specification which is measured by air permeability apparatus and its unit is cm2/gr, while specific surface is measured by ...

Grinding iron ore pellets.Blaine no in iron ore grinding blaine no in iron ore grinding iron ore pellets and pelletizing processes pelletizing is a process that involves mixing very finely ground particles of iron ore fines of size less than 200 mesh with additives like bentonite and then shaping them into ...
Understanding Pellets and Pellet Plant Operations. Pelletizing is an agglomeration process which converts very fine grained iron ore into balls of a certain diameter range (normally 8mm to 20 mm, also known as pellets. These pellets are suitable for blast furnace and direct reduction processes.

Effect of iron ore ultrafine generation during grinding operations is inevitable, results to attains maximum surface area for pellet making is been studied by several researchers (S. Patra et al ...
Most iron ore processing plants produce concentrates with Blaine specific surface Investigation on the particle size and shape of iron ore pellet feed using ball mill and HPGR 909 areas of 500–1600 cm 2 g -1 .
Blaine number is a guide for checking adequacy of grinding of oxide raw material for making green pellets. Normally pellet plant engineers will use all three parameters. 1. sieve analysis of ground oxide raw material, 2. Blaine number &. 3. Drop test. to control operation. vinayak sathe.
The various advantages of iron ore pellets are given below. Iron ore pellet is a kind of agglomerated fines which has better tumbling index when compared with the iron ore and it can be used as a substitute for the iron ore lumps both in the BF and for DRI production. Pellets have good reducibility since they have high porosity (25 % to 30 %).
Blaine Number Of Iron Ore Grinding. ... For this the ore was ground in a ball mill to prepare pellet feed of fineness with respect to the surface area of grains as 1312 cm 2 /g 1678 cm 2 /g 2425 cm 2 /g and 3218 cm 2 /g. Additive Alkalinity of pellets is a desirable feature and the addition of the alkaline compound is more advantageous in view ...

the Blaine number [1, 4, 5]. However, the relationship between the Blaine number and the type of mineral is not yet well studied. Moreover, the effect of shape and size distribution of minerals, as well as the number of fine particles and iron in minerals on the Blain number, has remained unknown.
